crossover frequency, minor differences in the subjective peak dynamic of the low frequency range and in
the coverage of mid frequency band can be heard.
7. Sub Out Mono control
The control is normally set to its center (0dB) position.
This control is used to adjust the loudness level of the summed low-frequency audio signal of the two
channels “A” and “B”, which serves to feed a connected monaural sub woofer power amplifier. The “Mute”
switch attenuates the Sub Out Mono audio signal, which allows to easily check the entire sound
reinforcement system. The green “Signal” LED indicates the presence of an audio signal while the red
“Peak” LED lights when the audio signal is clipped inside the PowerMax230 which might result in distortion.
In case the “Peak” LED lights continuously, lowering the input “A” and input “B” level controls is
recommended to maintain the entire dynamic range.
8. Lo Out Stereo
The control is normally set to its center (0dB) position.
This control is used to adjust the loudness level of the low-frequency audio signals of the two channels
“A” and “B”, which serves to feed a connected sub woofer stereo power amplifier or two separate power
amplifiers, respectively. The “Mute” switch attenuates the Sub Out Stereo audio signal, which allows to
easily check the entire sound reinforcement system. The green “Signal” LED indicates the presence of
audio signals while the red “Peak” LED lights when the audio signals are clipped inside the PowerMax230
which might result in distortion. In case the “Peak” LED lights continuously, lowering the input “A” and
input “B” level controls is recommended to maintain the entire dynamic range.
9. Hi Out Stereo
The control is normally set to its center (0dB) position.
This control is used to adjust the loudness level of the connected full-range or mid-hi cabinet power
amplifiers. The “Mute” switch attenuates the Hi Out Stereo audio signal, which allows to easily check the
entire sound reinforcement system. The green “Signal” LED indicates the presence of audio signals while
the red “Peak” LED lights when the audio signals are clipped inside the PowerMax230 which might result
in distortion. In case the “Peak” LED lights continuously, lowering the input “A” and input “B” level controls
is recommended to maintain the entire dynamic range.
10. Power-On switch
The PowerMax230’s outputs employ high quality audio relays. This ensures that no switching noise or
any other noise deriving from erroneously or inadvertently separating the appliance from the mains will
cause any harm to the connected loudspeaker systems.
